French doors have decorative handles that could interfere with the operation of door blinds or shades, so you'll want to choose a window treatment that is not very deep with an outside mount. If you plan on regularly raising and lowering your shade, go cordless to avoid getting cords tangled up on the door handle while also increasing child and pet safety. If you plan on leaving the shade down, you should select the hold down brackets when customizing your blind. These are installed on the door to keep the bottom of the shade in place.
